PURPOSE:To obtain a precise sliding part having uniform lubricity and abrasion resistance and usable under completely oilless conditions, easily, by applying a composite coating film composed of an organic metal compound and an organic polymer to the surface coated with a porous coating film having ultrafine pores. CONSTITUTION:The surface of a sliding part 1 is coated with an ultrafine porous coating film 2 preferably having a Vickers hardness of >=200. Separately, an organic metal compound and an organic polymer (e.g. PVC resin, PVA, PE, ABS resin, PET, etc.) are dissolved or dispersed in a proper organic solvent, and the treating liquid thus obtained is applied to the porous coating film and heated to obtain a lubricating coating film 3. |
